A system for marking and identifying objects, particularly work implements such as tools and work piece holders required in manufacturing processes, which has modules (4) with electronically readable markings, which modules (4) are to be arranged on the objects (1) to be marked, as well as an evaluating device having at least one pick-up capable of reading the markings. Each module contains at least one oscillating circuit (5, 6, 7) to produce a characteristic resonant frequency or resonant frequency combination. The number of different resonant frequencies or resonant frequency combinations provided corresponds to the number of different elements in the selected characterizing code, and the resonant frequency or resonant frequency combination of each module (4) is selected according to one of these frequencies or frequency combinations. The modules (4), which are to be fixed to the object (1), are selected and arranged according to the elements necessary for the representation of the marking of the object (1) in the selected code.
System for marking and identification of objects, particularly work implements such as tools and work piece supports required in manufacturing processes, having modules with an electronically readable marking, which modules are to be arranged on the objects to be marked, and an evaluating device with at least one pick-up capable of reading the marking, whereby each module contains at least one oscillating circuit to produce a characteristic resonant frequency or resonant frequency combination, comprising:
System according to claim 12, wherein the support is formed by a portion of the object.
